[fix][broker]unify time unit at dropping the backlog on a topic by HQebupt · Pull Request #17957 · apache/pulsar

HQebupt · 2022-10-07T03:42:52Z

Motivation

The backlog quota in time does not work due to time unit inconsistency in dropping the backlog on a topic.
The unit of backlog quota limit in time is seconds.

pulsar/pulsar-client-admin-api/src/main/java/org/apache/pulsar/common/policies/data/BacklogQuota.java

Lines 47 to 52 in 8d13ff8

    
               /** 
        
                * Gets quota limit in time. 
        
                * 
        
                * @return quota limit in second 
        
                */ 
        
               int getLimitTime();

The time unit inconsistency is here as follows.

pulsar/pulsar-broker/src/main/java/org/apache/pulsar/broker/service/BacklogQuotaManager.java

Lines 221 to 224 in 8d13ff8

    
           // Timestamp only > 0 if ledger has been closed 
        
           if (ledgerInfo.getTimestamp() > 0 
        
                   && currentMillis - ledgerInfo.getTimestamp() > quota.getLimitTime()) { 
        
               // skip whole ledger for the slowest cursor

                    // Timestamp only > 0 if ledger has been closed
                    if (ledgerInfo.getTimestamp() > 0
-                            && currentMillis - ledgerInfo.getTimestamp() > quota.getLimitTime()) {
+                            && currentMillis - ledgerInfo.getTimestamp() > quota.getLimitTime() * 1000) {


It's a confusing name :)

We should deprecate the old name limitTime and introduce a new one limitTimeInSec
Not for this PR, we can start a new discussion in the dev mailing list and make it only happen on the next major release @HQebupt
